How to use

Example

boshup.Interpolate([]byte, []byte, map[string]interface{}) ([]byte, error)

Code:

manifestBytes := []byte(`---
key: value`)

opsBytes := []byte(`
- type: replace
  path: /key
  value: ((variable))`)

variables := map[string]interface{}{
    "variable": map[string]map[string]string{
        "level1": {
            "level2": "level3",
        },
    }
}

result, _ := boshup.Interpolate(manifestBytes, opsBytes, variables)

fmt.Println(string(result))

Output:

key:
  level1:
    level2: level3

boshup.GetPath([]byte, string) (string, error)

Code:

manifest := `---
key:
  second_key:
  - name: first_array_element
    value: get-me-please
  - this: is-multi-line
    value: |
        ok
        this
        is
        weird`
path := "/key/second_key/name=first_array_element/value"

result, _ := boshup.GetPath(manifestBytes, path)

fmt.Println(result)

Output

get-me-please

boshup.SetPath([]byte, string, interface{}) ([]byte, error)

Code:

manifest := `---
key:
  second_key:
  - name: first_array_element
    value: get-me-please`

path := "/key/second_key/name=first_array_element/value"

valueToBeSet := map[interface{}]interface{}{
    "some-random-key": map[interface{}]interface{}{
        "level-2-random-key": "finally-value",
    },
}

result, _ := boshup.SetPath(manifestBytes, path, valueToBeSet)

fmt.Println(result)

Output:

key:
  second_key:
  - name: first_array_element
    value:
    some-random-key:
      level-2-random-key: finally-value

Bonus:

boshup.UpdateFromServiceDeployment([]byte, serviceadapter.ServiceDeployment) ([]byte, error)

Code:

boshManifest := bosh.BoshManifest{
    Name: "bosh-manifest-name",
    Releases: []bosh.Release{
        {
            Name:    "original-release-name",
            Version: "original-release-version",
        },
    },
    Stemcells: []bosh.Stemcell{
        {
            Alias:   "original-stemcell-alias",
            Version: "original-stemcell-version",
            OS:      "original-stemcell-os",
        },
    },
}

serviceDeployment := serviceadapter.ServiceDeployment{
    Stemcell: serviceadapter.Stemcell{
        Version: "service-deployment-stemcell-version",
        OS:      "service-deployment-stemcell-os",
    },
    Releases: serviceadapter.ServiceReleases{
        {
            Name:    "service-deployment-release1-name",
            Version: "service-deployment-release1-version",
            Jobs:    []string{"service-deployment-release1-job"},
        },
        {
            Name:    "service-deployment-release2-name",
            Version: "service-deployment-release2-version",
            Jobs:    []string{"service-deployment-release2-job"},
        },
    },
}

result, _ := boshup.UpdateFromServiceDeployment(boshManifestBytes, serviceDeployment)

fmt.Println(string(result))

Output:

name: service-deployment-name

- name: service-deployment-release1-name
  version: service-deployment-release1-version
- name: service-deployment-release2-name
  version: service-deployment-release2-version
